Description

BACKGROUND

Field

Exemplary embodiments of the present disclosure relate to an indoor display apparatus of a vehicle and a control method thereof, and more particularly, to an indoor display apparatus of a vehicle, which includes a flip-dot display installed at the top of a cockpit module inside a vehicle and configured to output external environment information during autonomous driving such that the external environment information can be intuitionally transferred to a driver, and a control method thereof.

Discussion of Related Art

In general, an image display apparatus refers to an apparatus that outputs information as an image using a screen. The image display apparatus may include a general monitor as one of computer output apparatuses. Output data are mostly expressed as characters, symbols, figures, images, voice and the like. All data except the voice, among the above-described data, are recognized with the eyes. The image display apparatus temporarily displays such information through the screen.

Examples of such an image display apparatus include a CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), TFT-LCD (Thin Film Transistor-LCD), PDP (Plasma Display), flexible display, HMD (Head Mounted Display) and the like.

Recently, a flip-dot display has been developed, which rotates a flip disk having surfaces with different colors by changing the polarity of an electromagnet, thereby implementing a pixel.

The related art of the present disclosure is disclosed in Korean Patent No. 10-1487904 published on Feb. 4, 2015 and entitled “Flip Dot Display Element using Electromagnet and Assembly Module Thereof”.

An autopilot system is embedded in various driving units for a driver, and performs autonomous driving through driving location search. The auto-cruise system is mainly applied to a ship, airplane and the like. Recently, the autopilot system is also applied to a vehicle that travels on the road, and informs a user of various pieces of information such as a traveling route and road congestion through a monitor, or autonomously drives the vehicle or controls the traveling state of the vehicle.

As such, an autonomous vehicle having the autopilot system mounted therein provides external environment information to a driver during autonomous driving, such that the driver can recognize surrounding circumstances during activities other than driving.

However, when the environment information is provided through an indoor ambient light, the visibility may be degraded in the daytime. When the environment information is transferred through speaker sound, the intuition may be degraded because the recognition of space perception such as directivity is insufficient.

FIG. 1 is a block configuration diagram illustrating an indoor display apparatus of a vehicle in accordance with an embodiment of the present disclosure, FIG. 2 is a diagram illustrating that the indoor display apparatus of the vehicle in accordance with the embodiment of the present disclosure is mounted, FIG. 3 is a side cross-sectional view illustrating that the indoor display apparatus of the vehicle in accordance with the embodiment of the present disclosure is mounted, FIG. 4 is a diagram for describing a detection region of a front detector in the indoor display apparatus of the vehicle in accordance with the embodiment of the present disclosure, and FIG. 5 is a diagram illustrating an operation state of the indoor display apparatus of the vehicle in accordance with the embodiment of the present disclosure.

As illustrated in FIGS. 1 to 3, the indoor display apparatus of the vehicle in accordance with the embodiment of the present disclosure may include a vehicle state inputter 10, a front detector 20, a flip-dot display 50, an illuminator 60, a controller 40 and an illuminance sensor 30.

The vehicle state inputter 10 may receive the operation state and traveling state of the vehicle, and provide the received information to the controller 40, such that the controller 40 can determine whether the vehicle is traveling in an autonomous driving mode and display the determination result.

As illustrated in FIG. 4, the front detector 20 may be installed at the front of the vehicle, detect a forward object ahead of the vehicle, and provide the detected distance and direction to the controller 40, such that the controller 40 can operate the flip-dot display 50 according to the detected distance to the forward object and the detected direction of the forward object.

As illustrated in FIG. 2, the flip-dot display 50 may be installed at the top of a cockpit module 70, and implement a pixel through a process of rotating a flip disk 55 whose front and rear surfaces have different colors, by changing the polarity of an electromagnet. With this structure, the volume and weight of the flip-dot display 50 may be reduced more than a structure that rotates flip disks using an actuator, which makes it possible to reduce the manufacturing cost thereof.

The cockpit module 70 is disposed in front of a driver seat and passenger seat in the vehicle, and serves to divide an engine room from the inside of the vehicle. The cockpit module 70 may include a steering wheel and an instrument panel, which are installed at the driver seat for a steering function of the vehicle, a glove box and a passenger seat airbag device, which are installed at the passenger seat, and a display device, an audio device and an air conditioner which are installed at the center fascia.

As illustrated in FIG. 3, the flip-dot display 50 may be installed at the top of the cockpit module 70 inside a windshield 80 such that a main display 75 installed at the front surface of the cockpit module 70 and a viewing angle of a driver are distinguished from each other, and include a clear cover 57 for preventing foreign matters.

The illuminator 60 may be installed around the flip-dot display 50, and illuminate the surface of the flip-dot display 50 so as to obtain an ambient light effect. Furthermore, the illuminator 60 may reflect and display the light of the illuminator 60 while the pixels of the flip-dot display 50 are rotated, thereby improving the visibility in the nighttime.

Here, the front and rear surfaces of the flip disk 55 of the flip-dot display 50 may be set to have different reflecting characteristics (e.g. gloss and matt), which makes it possible to improve the light reflecting effect of the illuminator 60.

The controller 40 may receive the operation mode of the vehicle from the vehicle state inputter 10, receive the distance to the forward object and the direction of the forward object from the front detector 20, and operate the flip-dot display 50 and the illuminator 60.

Furthermore, when the operation mode of the vehicle is an autonomous driving mode, the controller 40 may operate the illuminator 60 in color according to the autonomous driving mode as illustrated in FIG. 5C, and operate the flip-dot display 50 to reflect the light of the illuminator 60, thereby informing the driver that the vehicle is traveling in the autonomous driving mode.

Furthermore, when the distance at which the forward object is detected falls within a preset distance, the controller 40 may operate the flip-dot display 50 as illustrated in FIG. 5A, according to the detected direction and movement of the forward object.

For example, when a pedestrian passes the front of the vehicle, the controller 40 may operate the flip-dot display 50 according to the direction in which the pedestrian passes, such that the driver can intuitionally recognize the approach of the pedestrian through a surrounding effect using operation noise, caused by sound which is generated while the flip disk 55 is rotated, and visual information displayed on the flip-dot display 50.

When the detected distance at which the forward object is detected falls within a warning distance, the controller 40 may operate the flip-dot display 50 while operating the illuminator 60 in a warning color as illustrated in FIG. 5B.

The illuminance sensor 30 may sense the ambient brightness of the vehicle and provide the ambient brightness to the controller 40. Thus, when the detected distance at which the forward object is detected falls within the preset distance in the case that the forward object is detected, the controller 40 may operate the illuminator 60 in the nighttime or a dark place according to the ambient brightness, and then operate the flip-dot display 50 to reflect the light of the illuminator 60 according to the detection direction and motion of the forward object, thereby improving the visibility in the nighttime.

As described above, the indoor display apparatus of the vehicle in accordance with the embodiment of the present disclosure may include the flip-dot display installed at the top of the cockpit module inside the vehicle, and output external environment information during autonomous driving, thereby obtaining the surrounding effect through the operation noise of the flip-dot display and the visual information. Therefore, the indoor display apparatus can not only intuitionally transfer the external information to the driver, but also improve the visibility in the daytime through the flip-dot display, thereby improving the visual information transfer effect.

FIG. 6 is a flowchart for describing a control method of an indoor display apparatus of a vehicle in accordance with an embodiment of the present disclosure.

As illustrated in FIG. 6, the control method of the indoor display apparatus of the vehicle in accordance with the embodiment of the present disclosure starts with step S10 in which the controller 40 receives a vehicle state from the vehicle state inputter 10, and receives a detection result of a forward object from the front detector 20.

After receiving the vehicle state in step S10, the controller 40 determines whether the vehicle is traveling, in step S20.

When the vehicle state received in step S10 indicates that the vehicle is initially started, the controller 40 may operate the flip-dot display 50 to output welcome animation.

When the determination result of step S20 indicates that the vehicle is not traveling, the controller 40 returns to step S10 to receive the vehicle state and the detection result of the forward object.

On the other hand, when the determination result of step S20 indicates that the vehicle is traveling, the controller 40 determines whether the operation mode of the vehicle is an autonomous driving mode, based on the vehicle state, in step S30.

When the determination result of step S30 indicates that the operation mode of the vehicle is the autonomous driving mode, the controller 40 may operate the illuminator 60 in a color according to the autonomous driving mode as illustrated in FIG. 5C, and operate the flip-dot display 50 to reflect the light of the illuminator 60, thereby informing the driver that the vehicle operates in the autonomous driving mode, in step S40.

When the determination result of step S30 indicates that the operation mode of the vehicle is not the autonomous driving mode, or after the controller 40 informs the driver that the vehicle operates in the autonomous driving mode in step S40, the controller 40 determines whether the detected distance is less than a preset distance, according to the detection result of the forward object, in step S50.

When the determination result of step S50 indicates that no forward object is detected or the detected distance is not less than the preset distance, the controller 40 may return to step S10 to continuously receive the vehicle state and the detection result of the forward object.

However, when the detected distance is less than the preset distance, the controller 40 operates the flip-dot display 50 according to the detected direction and motion of the forward object, in step S60.

As illustrated in FIG. 2, the flip-dot display 50 may be installed at the top of the cockpit module 70, and implement a pixel through a process of rotating the flip disk 55 whose front and rear surfaces have different colors, by changing the polarity of the electromagnet. With this structure, the volume and weight of the flip-dot display 50 may be reduced more than a structure that rotates the flip disks using an actuator, which makes it possible to reduce the manufacturing cost thereof.

Furthermore, the front and rear surfaces of the flip disk 55 of the flip-dot display 50 may be set to have different reflecting characteristics (e.g. gloss and matt), which makes it possible to improve the light reflecting effect of the illuminator 60.

For example, when a pedestrian passes the front of the vehicle, the controller 40 may operate the flip-dot display 50 according to the direction in which the pedestrian passes, such that the driver can intuitionally recognize the approach of the pedestrian through a surrounding effect using operation noise, caused by sound which is generated while the flip disk 55 is rotated, and visual information displayed on the flip-dot display 50.

While operating the flip-dot display 50 according to the detected direction and motion of the forward object in step S60, the controller 40 determines whether the detected distance to the forward object is less than a warning distance, in step S70.

When the determination result of step S70 indicates that the detected distance is less than the warning distance, the controller 40 operates the flip-dot display 50 while operating the illuminator 60 in a warning color as illustrated in FIG. 5B, in step S80.

On the other hand, when the determination result of step S70 indicates that the detected distance is equal to or more than the warning distance or after the controller 40 operates the illuminator 60 in the warning color in step S80, the controller 40 determines whether the object detection has been canceled, in step S90.

The controller determines whether the object detection has been canceled because the detected distance increased or no object was detected according to the detection result, in step S90. When the determination result of step S90 indicates that the object detection is not canceled, the controller 40 returns to step S60 to continuously operate the flip-dot display 50 according to the direction and motion of the forward object.

On the other hand, when the determination result of step S90 indicates that the object detection has been canceled, the controller 40 stops the operations of the flip-dot display 50 and the illuminator 60, in step S100.

The controller 40 may receive the ambient brightness from the illuminance sensor 30. When the detected distance at which the forward object is detected falls within the preset distance, the controller 40 may operate the illuminator 60 in the nighttime or a dark place according to the ambient brightness, and then operate the flip-dot display 50 to reflect the light of the illuminator 60 according to the detected direction and motion of the forward object, thereby improving the visibility in the nighttime.

As described above, the control method of the indoor display apparatus of the vehicle may include the flip-dot display installed at the top of the cockpit module inside the vehicle, and output external environment information during autonomous driving, thereby providing the surrounding effect through the operation noise of the flip-dot display and the visual information. Therefore, the control method can not only intuitionally transfer the external information to the driver, but also improve the visibility in the daytime by the flip-dot display, thereby improving the visual information transfer effect.

The examples described above provide an indoor display apparatus of a vehicle, which includes a flip-dot display installed at the top of a cockpit module inside a vehicle and configured to output external environment information during autonomous driving such that the external environment information can be intuitionally transferred to a driver, and a control method thereof.
